Had a few desyncs online whree I end up playing vs my inputs mirrored

Steps to reproduce:
Just playing Ranked Match queue.

Expected Results:

Actual Results:
My opponent reported getting a black screen before the 1st round started. I appear to be playing vs them… but then I realise they are acting weirdly, and their character is in fact just repeating my inputs. I continue to KO their whole team, and then it hung for a while on the results screen. But then I think does give me the win (maybe?)

Replay files:

Game Version:
Steam, current, windows.

Notably I have only had this happen vs people on my friends list in game.

Ok it’s happened to me twice now vs 2 players (2 times each).

Vs Kingheim x2
and
Vs TheZipBon x2

Both on my friends, both on PC, I think Zip is on Linux, Kingheim on Windows…

Friend match vs TheZipBon works fine btw.

When the bug happens, I will also see ping=1
